Afs-rarlis PATENTv FFICE JESSE I. GOSNELL, 0F ST.r JOSEPH, MISSOURIfLo'ooisiOTIYl"J WEDGE BOLT ATTACHMENT Application filed. `ll/Iay 29,

yMy invention relates to improvements in Y adjusting devices for the'bearing ,boxes of locomotives and it has for its primary object 4 toprovide a very compact, simple and highly efficient device for thepurpose specified; one which involves a' minimum number Vof parts andwhich' can'be readily applied tothe binder at the lower end of the"pedestal within which the driving box is' located,-and this j withoutmodification of the parts referred to and without modification of theadjusting wedge and worm shaft commonly employedit being v.possible toapply my device using the same bolts that are now provided in allconstructions now for supportingthe device which my invention isintended yto supplant.

A further object of the invention is to provide a device for the purposeindicated vwhich can beV applied 'without the necessity of re- 20 movingthe bind-er, which isv of considerable advantage over priorfde'vices ofthis kind.

The invention also resides'in certain novel features of construction,combination and arrangement of` the'v various parts and in modes ofoperationy-all of which will be readilyl understood and appreciated bythose skilled in the art yuponreference to the accompanying drawings inconnection with the 'following detailed descriptive matter.

While the preferred form of the invention has been ,chosen for purposesof illustration,

asrequired by the patent statutes,-yet it isk Vto be understood Athat'the 'invention is susceptible of considerable'change andmodificationwithin the spiritfand scope ofthe subject matter claimedhereinafter.

In the drawings, wherein the same refer,- ence characters have been used'to designate the same parts in all views,

Figure l is a fragmentary elevational view showing a portion of theengine frame and illustrating the application of my invention to theadjusting wedge of one of the bearing boxes and its associated carryingpedestal;

Figure 3 is a cross sectional View taken on the line 3-3 of Figure l;and

Figure 4 is a group perspective View of the elements detached.

1929. serial No. 366,939.

Referring specifically to the drawing, numeral l designates a portion ofthe locomotive frame; 2 the so called pedestal, having the upright bars2a, 2b at the sides between which reciprocates the driving box ofbearing box 3 within which is shown the axle 49. Surmounting the bearingbox 3 is the saddle 5 which transmits the weight of the frame to the box3 vthrough the leaf spring 6 in the usual manner.y This is a more orless conventional construction which varies in the differentlocomotives.

It is also customary to provide the bar 2b of the pedestal with a facing0r bushing-like wear face 8 which is adapted to seat in the groove 9 ofthe bearing box 3, as indicated. The pedestal bar 2a at the oppositeside is provided with a similar face plate, which is designated at l0and is received in a groove 9a at the opposite side of the bearing box3. The wedge 10 has a tapered surface 10a corresponding to the angle ofincline of the inner face 2a of the bar'2a, as clearly indicated inFigure l. Thus, adjusting of the plate or member l0 through theinstrumentality of the worm ll depending from the lower endthereof,prevents transverse play 0f the box 3 in the pedestal 2. Theworm 1l extends through the bar or binder block 12 which, as

shown, closes the lower end of the pedestal 2 and maybe secured by meansof bolts 13 and nuts lil, as indicated. Obviously7 the hole l2 in thebinder block l2, through which the worm 11 extends, will be slightlyelonga'ted to -allow for slight movement in the direction of the widthof the box 3, as the wedge 10 is moved. Y

The foregoing construction is more or less standard and no novelty isclaimed therefor. y

My invention resides in the provision of a v'novel U-shapedbracketmember 20 having lateral arms 2l which have suit-able holes toreceive the bolts 13, 22 extending from the pedestal l frame 2 wherebythe U-shaped member may be securely bolted beneath said frame andagainst the binder block 12. The U-shaped frame 2O is provided with aninner Ushaped plate 23, which is secured against kthe arms of the firstmentioned U-shaped plate by means of bolts 24. It is to be noted
